GHSA-rc4v-99cr-pjcm
Prototype Pollution in ali-security/mongoose
Impact
This vulnerability causes a Prototype Pollution in document.js, through functions such as findByIdAndUpdate(). For applications using Express and EJS, this can potentially allow remote code execution.
Patches
The original patched version for mongoose 5.3.3 did not include a fix for CVE-2023-3696. Therefore the existing version @seal-security/mongoose-fixed version 5.3.3 is affected by this vulnerability (though it is protected from CVE-2022-2564 and CVE-2019-17426). To mitigate this issue, a @seal-security/mongoose-fixed version 5.3.4 has been deployed. Note that this version is compatible with the original mongoose version 5.3.3, not version 5.3.4
